Brisket

The cut where 'done' is a feel rather than a number, and where two briskets of identical weight can finish two hours apart for no reason anybody can observe in advance.

What it is

Form: Whole muscle
Typical weight: 4.0–7.0 kg
Typical thickness: 60–120 mm
Cut: Packer brisket

Why it behaves as it does

The reason experienced cooks describe brisket by probe feel rather than temperature is that the temperature at which any given brisket becomes tender varies by several degrees between animals. A number would be more precise and less accurate. BBQHQ still holds no retrieved duration source for brisket — the search that found four new timing publishers found none who publish one.

When is it done?

Food-safety endpoint

Food Standards Agency
The Food Standards Agency states that whole cuts of red meat such as steaks can be served pink, rare or bloody and will be safe to eat as long as the surface has been adequately seared. It gives no internal temperature for this case, so there is no figure here to cook to — the searing of the surface is the condition.
The rule and its source
In England, Wales and Northern Ireland the Food Standards Agency states that whole cuts of red meat such as steaks may be served pink, rare or bloody, on the condition that the surface has been adequately seared. No internal temperature is given for this case.
Well established
- Food Standards Agency — States this directly
  “red meat such as steaks can be served pink, rare or bloody and will be safe to eat as long as the surface has been adequately seared”
  What it covers:
  The document states its own reach: 'Applies to England, Northern Ireland and Wales'. Food Standards Scotland publishes separately and, as recorded separately, does not make this statement.
  The permission is CONDITIONAL and the condition is the whole rule: the surface must have been adequately seared, because on a whole cut the contamination is on the surface. A reading that drops the condition has changed the guidance into something else.
  Shape:
  No figure is given, and none is implied. This is a statement about a FORM rather than a temperature, which is why BBQHQ had to be able to record a rule about form at all before this could be held without inventing a number to hang it on.

USDA Food Safety and Inspection Service
In the United States, whole cuts of beef, pork, lamb and veal — steaks, chops and roasts — should reach 145 °F (63 °C), followed by a rest of at least three minutes before carving or eating.
- 63 °C (145 °F) — measured at the centre of the thickest part, away from bone and fat.

Health Canada
In Canada, beef, veal and lamb pieces and whole cuts are given a safety figure for each doneness level: 63 °C (145 °F) medium-rare, 71 °C (160 °F) medium and 77 °C (170 °F) well done. Mechanically tenderized beef and veal should reach 63 °C and be turned at least twice during cooking.

- 71 °C (160 °F) — measured at the centre of the thickest part.
- 77 °C (171 °F) — measured at the centre of the thickest part.
The rule and its source
In Canada, beef, veal and lamb pieces and whole cuts are given three safety figures by doneness: 63 °C medium-rare, 71 °C medium and 77 °C well done. Mechanically tenderized beef and veal are given 63 °C and must be turned at least twice during cooking.
Well established
- Health Canada — States this directly
  “Pieces and whole cuts, for example, steaks and roasts medium-rare 63 145 medium 71 160 well done 77 170”
  Shape:
  A safety chart that speaks in doneness, which is unusual and useful. Most authorities give one safety figure and leave doneness to the cook; Canada publishes the ladder, so a Canadian reader choosing medium-rare is choosing inside official guidance rather than against it.
  The mechanically tenderized row carries a handling instruction rather than only a temperature, which matches BBQHQ's existing claim that tenderised meat behaves like mince.

Wash a thermometer stem in hot soapy water before and after each use, and do not put the head in water.

  “Make sure to clean the stem of your food thermometer with hot soapy water before and after each use. Do not immerse the head in water.”
  Before and after, not just after. a probe that went into an undercooked bird and then into the next one is a cross-contamination route BBQHQ's food-safety model already recognises between surfaces and hands, and has never described for the instrument that touches every piece of meat on the grate.
  The head exclusion is an equipment instruction rather than a hygiene one — electronics — and is recorded here because it is in the same sentence and separating them would misquote the source.

Texture endpoint — how you actually know

Probe tender — like pushing into softened butter

A probe slides into the thickest part of the flat with no resistance at all, and the point wobbles when the whole piece is lifted. Two briskets of identical weight can reach this two hours apart, which is why every experienced account describes the feel rather than a number — and why the temperature below is a guide to when to start checking rather than a target to cook to.

Indicative only: 85–91 °C (185–196 °F). This is not a target to cook to — the feel decides.

Where this comes from

Brisket becomes tender when its collagen converts to gelatin, which Texas A&M Meat Science gives as requiring an internal temperature of 185 to 195 °F (roughly 85–91 °C) — far above the safety endpoint for the same meat, and a texture endpoint rather than a doneness preference.

“it requires a higher internal temperature (ranges from 185 to 195°F) to achieve this conversion”
A texture endpoint — where connective tissue becomes soluble. Not a doneness preference and emphatically not a safety figure.
What it covers:
Stated for collagen generally, in the context of high-connective-tissue barbecue cuts such as brisket and pulled pork.
Roughly 25 °C above the USDA whole-cut safety endpoint for the same meat. Both are correct; they answer different questions.

“tend to have high levels of connective tissue, which require longer cooking times at low temperatures”
Point and flat are the two muscles of a packer brisket, and they differ materially in fat.
A flat and a whole packer are not the same cook, which is why they are held as separate applicability cases rather than one.

How long it takes

Brisket, low and slow

Estimated cooking window

8h 50m–15h 30m

Low confidence

Why this is a range, not a number

Weight varies within the range this covers
Cookers hold temperature imperfectly
Individual animals and pieces differ
Thickness varies between pieces
Outside temperature and wind
How often the lid comes off

Cook to the endpoint, not to the clock. The window tells you when to start checking.

What this rests on

BBQHQ publishes a window for this cook.

Observations: 5
Documents: 4
Publishers timing this cook: 1

Texas A&M University, Department of Animal Science (Meat Science)

Also on this page, supplying endpoints or doneness rather than timings: AmazingRibs.com · United States Department of Agriculture, Food Safety and Inspection Service. They are not a second opinion about how long the cook takes.

Why confidence is not higher

Only one source applies to these conditions.
The window is BBQHQ's arithmetic on a source's per-unit rate, not a window the source published.
The endpoint is well established; the timing behind it is not. Cook to the endpoint.
No source states the weight of the food.
At least one source does not state the cooker temperature.

How the sources were combined

Four new duration publishers were found and none of them publishes a brisket time. A university meat science department publishes the PHYSICS instead, which turns out to be more useful. Texas A&M gives the pit range as 200–250 °F by indirect cookery, and collagen conversion — what 'tender' actually means for this cut — as 185–195 °F. Those are a COOKER temperature and a TEXTURE endpoint, and neither competes with the USDA's 63 °C whole-cut SAFETY figure, which this brisket passes in the first few hours and which tells a cook nothing about when it is ready. Three outcome concepts, three correct numbers, held apart. On duration the source gives a rate — one hour per pound — and explicitly frames it as a general rule rather than a finding. The window below is BBQHQ multiplying that rate across this profile's 4–7 kg band; it is arithmetic on somebody else's rule of thumb, it is labelled as such in the confidence reasons, and it is not a figure Texas A&M published.

What makes the window as wide as it is

Also relevant to brisket

Afterwards

Cooling, keeping and reheating what is left is general guidance for barbecue leftovers. Neither UK authority publishes anything specific to brisket, and BBQHQ does not invent a distinction they do not make.

Traditions that cook it

Texas barbecue
A regional US barbecue practice centred on beef, particularly brisket, cooked for many hours at low temperature with wood smoke. Texas contains several distinct regional styles rather than one.

What we don't know about this

The cooking time here traces back to a single publisher. A second, independent source would raise confidence in it; none has been found yet.
